Abstract
Methods and systems are provided for monitoring steering gear overtravel in rack and pinion steering systems. The provided systems and methods introduce a change in the length of the fastener that attaches an inner tie rod ball joint housing within a steering gear rack bar. The provided systems and methods also monitor the disengagement of that fastener (also referred to as overtravel and as rack travel) to generate flags and provide them to the Controller Area Network (CAN) bus of the vehicle.
